IIVIPROVl-D APPARATUS FOR WASHING AND AMALGAMATING GOLD.

It is a ad exact description thereof, reference being contemplated making projections on the prohad to the accompanying` drawings, and to the jections I, so as to agitate the water, &c., in

The said receptacle for heating thc water, quartz, &c., before passing through the machine, I-contemplate making in the form of a drum, and have it revolve, and made with projections running lengthwise or otherwise on the inside of the drum, to force the mercury in contact with the quartz, gold, 81o., as the drum revolves. l contemplate having the quartz remain in this air-tight revolving drum (which may revolve in or over afurnace or fire) about a half-hour, after which it is allowed to pass through the machine A.

I niakea working machine with ahouttwelve of the channels H, and when deemed necessary I allow the quartz, &c., to run through two of the machines, in order to secure a more perfect amalgamation of the gold.
